RAIL-FASTENING.

Specification of Letters Patent.

' Patented June 11, 1907.

Application filed September 26. 1906. Serial 1:... 36,273,

fastenings, and consists in certain novel constructions and combinationsof parts as will be hereinafter described and claimed.

In the drawing Figure 1 is a top plan view of the invention. Fig. 2 is across-section on about line 22 of Fig. 1. Fi 3 is a detail top plan viewof aporti'on of t 1e tie. I Fig. 4 is a detail vertical section-illustratin gthe ap plication of one of the bolts to its slot in thetie, and Fig. 5 is a detail view illustrating the application of theother bolt to its tie slot.

The tie A is. adapted to receive the rail 13 and may be provided at itsside edges with the depending flanges'A, as will be understood from Fig.2 of the drawing. The rail B rests flat upon the tie between theoppositeslots C and/D, the slots D being preferably arranged in pairs, as willbe understood from Figs. 1 and 3 of the drawing. These slots C andD'receive the bolts E and F for holding the clamp plates G and H, asshown in Figs. 1, 2 and 3. Ordinarily the clamp plate H is arranged atthe outer side of the rail and the clamp plate G at the inner side ofthe rail so for convenience of reference I will refer to the plates Hand G, respectively, as the outer and inner clamp plates. These clampplates are recessed in their inner sidesat h and g to receivethe base ofthe rail B and are extended at their ends at h" and g to bear againstthe web of the rail and thus insure the holding of the rail by the clampplates even should the.

bolts become so loosened as to permit the shoulders at h and g to rideabove the outer edges of the rail base so that the clamp plates willoperate to-secure the rails as long as said plates are held by theirbolts whether the nuts be tight or loose. I f

The 'bolts E are secured in the slots G and the bolts F in the slots Dand these slots are provided at one end with enlarged portions C and Dto receive the heads of the bolts and said slots are elongated in adirection at a right-angle to the rail and the enlarged portions C andDof the slots are at the cor-. responding ends of their respective slots,so thatwhen the bolts are inserted the reduced or smaller ends of theslots are at the outer ends thereof with respect to the outer side ofthe track so that the bolts will be held as against any tendency by thespreading of the rail againstadjustment to the enlar ed ends of theirrespective slots. The bolthas its head E adapted to be inserted throughthe enlarged portion C of the slot C and the shank of the bolt adjacentto the headE is squared at E with its square of such size as to permitit to be moved along the slot C and its diagonals of such length as topermit the bolt to fit at its corners in notches C in the oppositesidestof the slotCwhen the bolt is so turned as will be understood fromFig. 3 of the drawin so that when in this adjustment the bolt will belocked from movement within the slotas will be unders ood from Fig. 3 ofthe drawing. Ordinarily I provide several notches C so the bolt may besecured at difi'erent points within the slot C as desired. This'bolt Eextends up through the clamp plate G and thence through awvasher G uponsaid clamp plate and receives the nut e as shown in Figs. 1 and 2 of thedrawing. In Fig. 5, I show the bolt in dotted lines as inserted throughthe enlarged portion C of the slot C- and in fulllines as held withinthe slot C by the fitting of its corners in the notches in the saidslot, as will be understood from Figs. 3 and 5.

The slot D has its enlarged portion D in the form of asemici'rcle, thissemicircular end D permitting the insertion of the head F of the bolt Fwhen the latter is turned to inclined position, as shown in Fig. 4,after which the bolt may be adjusted along the slot I) to the positionindicated in dotted lines in Fig. 4, and then passed u through theopening H in the clam plate I, thence rounded side sloped at d tofacilitate the introduc'tion of the bolt head. as'best shown in Figs. 2and 4.

What I claim is 1...Tl1e combination with the rail and the clamp plateG, of a bolt E and a tie having a slot notched in its opposite walls toreceive the corners of the boltshank whereby to lock of the bolt head,the rounded side of'said enthe bolt when applied to secure the clamplarged portion being sloped to facilitate the 10 plate, substantially asset forth. mtroduction of the head,substantially as set 2. Thecombination with the rail, the forth. clamp plate and the bolt forsecuring the AUGUSTUS W. AVERY. same, of a tie plate having 'a slotreceiving Witnesses:

said bolt and provided with an enlarged J. W. LANE,

semicircular end portion for the introduction C. L. BARWIGK.
